<h1>项目场景：</h1>
<p><code>提示：这里简述项目相关背景：</code></p>
<p>例如：项目场景：示例:通过蓝牙芯片(HC-05)与手机 APP 通信，每隔 5s
传输一批传感器数据(不是很大)</p>

<h1>问题描述</h1>
<p><code>提示：这里描述项目中遇到的问题：</code></p>
<p>例如：数据传输过程中数据不时出现丢失的情况，偶尔会丢失一部分数据 APP
中接收数据代码：</p>
<div class="sourceCode" id="cb1"><pre class="sourceCode c"><code class="sourceCode c"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a>@Override</span>

<span id="cb1-5"><a href="#cb1-5" aria-hidden="true" tabindex="-1"></a>    <span class="op">}</span></span></code></pre></div>
</section>
<section id="原因分析" class="slide level1">
<h1>原因分析：</h1>
<blockquote>
<p>提示：这里填写问题的分析：</p>
</blockquote>
<p>例如：<code>Handler</code> 发送消息有两种方式，分别是
<code>Handler.obtainMessage()</code>和
<code>Handler.sendMessage()</code>，其中 <code>obtainMessage</code>
方式当数据量过大时，由于 <code>MessageQuene</code> 大小也有限，所以当
<code>message</code>
处理不及时时，会造成先传的数据被覆盖，进而导致数据丢失。</p>
</section>
<section id="解决方案" class="slide level1">
<h1>解决方案：</h1>
<blockquote>
<p>提示：这里填写该问题的具体解决方案：</p>
</blockquote>
<p>例如：新建一个 <code>Message</code> 对象，并将读取到的数据存入
<code>Message</code>，然后
<code>mHandler.obtainMessage(READ_DATA, bytes, -1, buffer).sendToTarget();</code>换成
<code>mHandler.sendMessage()</code>。</p>
